FoLLzoT HOSE REEL FOR FIRE EXTINGUISHING APPARATUS Filed April 25, 1936 2 Sheets-Sheet 2 Patented Aug. l0, 1937 PATENT OFFIQE Hose anni. non man EXTINGUISHING APPARATUS Ernest Foiliot, La Rochelle, France Application April 23, In France 6 Claims.

The invention as hereinafter described refers to a re hose reel so arranged that when the re hose is wound ou, this causes the outlet for the supply of the extinguishing water, liquid or gas to open, thereby allowing a very quick setting in operation oi the apparatuses adapted to extinguish the fire; this results in a most important saving of time in disasters of this sort where the slightest delay may be the cause of important if not of irreparable losses.

The device is provided with a safety locking means which makes it almost impossible to have any interruption in the service of the apparatus; the rst pulling motion exerted upon the hose l5 having for eiect to secure at once the opening o the delivery mechanism.

'Heretofore a nre extinguisher most commonly comprises:

lst-A reel on which is wound up one or several O hose members, the said hose being provided at d one. of. its ends with part of a so-called symmetrical quick connecting joint piece and at the other end with a water pipe or lance;

2nd-,-A water supply most frequently constituted by a cock or valve which is secured to the delivery pipe and whose free outlet is provided with a part to kbe connected to the symmetrical joint of the hose.

After the said hose has been completely wound o fl", the joint thereof is quickly secured to the one of the valve; the said operations, although they are quickly performed, require a certain time and it frequently happens that delays were due to the fact that the joints did not enter at once in 5 one another, or that the valves or cocks whose movable parts were, after having remained unused for a somewhat long period of time, oxidized or sticked together, required to be inspected, unlocked or taken to pieces and this, in case of a disaster, might have had the most fatal consequences.

Ihe device according to the present invention does away with all these inconveniences and has the advantage of being capable of being maintained in a good state of operation without it being necessary to interrupt the supply of the apparatuses. The reel, the tight parts and all of the moving members can, at any moment, be taken apart for the purpose of being cleaned,

lubricated and to receive every care for repairs which are usually required by moving parts. Such a device is of the most importance on ships, for instance, where the inspection of a re valve requires the whole or part of the re extinguishing service on board to be stopped.

1936, Serial No. 76,062 May 4, 1935 An embodiment of the invention is represented, by way of example, diagrammatically in the acccmpanying drawings in which:

Fig. 1 is a sectional View of the whole of the reel or winding oi device in the closing position.

Fig. 2, half a front view and half a section made through the axis of the supply pipe.

Fig. 3 is a part section in the opening position.

Fig. 4 is a part section of a detail of the device for locking the yoke or rider.

Fig. 5 is a part section of a detail of the device for unlocking the yoke.

Fig. 6 is a perspective view.

The reel or winding off device comprises a body I, made of bronze or other metal or material suitable for the liquid or gas as employed for extinguishing the fire, the said body being rigidly secured to a fixed or steerable support. The same also comprises a valve secured to the bottom and in the middle of the body I, a movable part 2 screwed at 5 to the body I and a hub 3 adjusted and ground to the conical part of the member 2. The said hub 3 is `maintained in position by the washer I8 and the nut 4. A two-branch handle I2 is adjusted upon a square part at the end of the member 2 and is maintained in position by the washer I3 and the screw I4.

The tightness of the'member 2 when the same leaves the body I is secured by the washer I0 made of some plastic matter and the stuing-box nut 8. To thewalls of the hub are secured the cheeks Il of the reel. Between the latter is adjusted and secured an interrupted circular sheet iron plate 21 between the spaced ends of which passes the outlet pipe 23 which receives the part of. the joint connecting itself to one of the ends of the hose.

The washer I8, adjusted to one part of the member 2, is formed with an oiset for supporting the axis I1 of the yoke I6 between the branches of which is engaged, in the closing position, one of the ends of the rod I9, the other end of which is maintained in Contact with the external face of the stuffing-box nut 8 under the influence of the spring 20 bearing upon the washer 2|. A tight washer 6 prevents, in the closing position, any introduction of the extinguishing liquid or gas into the threads of the member 2.

The ports 24 connect the interior of the member 2 with the annular space 25 and the outlet pipe 23.

The liquid or gas supply takes place through the pipe 26 cast in one part with the body.

The said gures are given by way of example only, the form of the reel or winding off dlevice, of the valve, of the cheeks, the inlet and outlet connecting system can be modified so as to meet with particular conditions of use.

The operation of said apparatus is as follows:

The apparatus being in the closing position (Fig. l), the pull exerted upon the hose so as to secure the winding off has for effect to unscrew the member 2, connected at this moment to the l hub, through the introduction of the end of the rod i9 between the branches of the yoke I6 connected on its turn with the washer I8 centrally provided with a square l adjusted upon the member 2; at this moment, the said member 2 l5 occupies in the body the position indicated in Figures 3 and 4 and the liquid coming through passes the now open valve `Tand enters member 2.

When the member 2, after a few turns, has moved to the right to an amount corresponding to the length of therod I9 engaged between the branches of the yoke, the hub then revolves loosely on the part 2 which is itself immobilized by the fact that the shoulder 9 bears upon the 25 tight washer I0. l f

A reduced stress, to operate the reel, allows the complete unwinding of the hose. At this moment, the liquid or gas enters the same and can be at once directed towards the place in fire.

After use, in order to set the apparatus for the purpose of a new use, the yoke l5 is folded `down (position shown in Fig. 5); the supply of liquid is closed in turning in the required direction the handle I2 and the hose is wound up. It is 3.5 then only necessary to bring back the yoke opposite to the rod i9 which, during the closing position by hand has again come out, and to bring down the yoke over the rod.
